COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 661.110, dated November 6, 1900.

Application tiled May 6, 1897. Serial No. 636,295. (No model.)

To all whom t may concern:

Be it known that we, HARRY SCHWERD- FEGER and JOSEPH KAYSER, citizens of the United States, residing-at the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cooling Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specication.

This invention has relation to apparatus for cooling beers and other liquids, and has for its object to provide a simple and efficient construction whereby the cooling operation shall be expeditiously effected without expo-v sure of the liquid to the external atmosphere, as will hereinafter appear. A

In the drawings, Figure l is a longitudinal vertical section of the cooling apparatus. Fig. 2 is a transverse vertical section thereof as on the line a: @cof Fig. l. Fig. 3 is a detail of the central pipe, showing a portion of the external coil thereon.

A, B, and C represent three concentric pipes arranged to form the central chamber c and the annular chambers b c. These pipes are of any suitable length and diameter for their intended purposes, and they may, if necessary or desirable, be made in sections coupled or jointed together, as at a b'. o', 'The respective ends of the pipes have fitted thereto globe-like sections a2 b2 c2, respectively, which are so arranged that the central chamber terminates in enlarged chambers a3, while the annular chambers terminate in the expanded chambers b3 c3, respectively. The sections a2, b2, and c2 are preferably made Ieach in twosectionscou pled together midway lof its ends.. of the inner section are connected by a screw dap-joint l, those of the second section are yconnected by a screw coupling-ring 2, while .those of the remaining or outer section are provided with external anges 3, that are lbolted together. By this construction the parts may be readily disconnected as occasion may require. The interior sections a2 .b2 are connected at their outer extremities by .a neck d, while the exterior sections c2 have cou pled thereto pipes E E,respectively,which In the present instance the parts thus each communicate with the adjacent central and outer chambers, respectively. The pipe E is connected with a source of cold water or other cooling-agent supply, while the other pipe El leads to a suitable point of discharge. l

On each of the intermediate end sections b2 is formed a neck ff', which extends through the adjacent ontersection and is clamped thereto, being provided with a flan'gef2 and coacting screw-ringfs. One,f, of these necks is connected with a pipe leading from the beer-supply, say, while the other, f', is connected with a pipe leading to a suitable point of discharge.

From the foregoing it will be seen that the beers, dac., enter by way of the neckf into the adjacent end chamber, thence into and along the chamber b to the other end chamber b3, and pass by way of the neck f to the discharge-pipe; also, that the cold water, &c., will pass by way of the pipe E into the central end chamber c3 and the outer chamber c3, thence through the central chamber a and the outer concentric chamber c, so as to reduce the temperature of the beer, dac., in the interposed chamber. The cold water, dac., passes onward to and through the communicating end chambers and thence to and through the discharge-pipe E.

It will be observed that the cold and hot liquids flow in opposite directions and that therefore the temperature of the hot liquid has been considerably reduced before the initial action of the incoming water thereon, and, further, that by reason of the expanded end chambers a comparatively large cooling surface is presented to the hot liquid at its points of ingress and egress to and from the apparat-us,there`by insuringa rapid and elective cooling of the liquid. It will also be observed that the beers, dac., during the cooling operation are entirely excluded from the atmosphere, thereby obviating all liability of infection or contamination from external sources.

As a simple and etlicient means to retard the progress of the beer, Snc., as it passes through the chamber b, and thereby subject it still more thoroughly to the action of the cooling agent, we prefer to encircle the cen- IOO through and clamped to the adjacent outer sections, the said sections being each made in two parts detaehahly coupled together in the body thereof, substantially as described.

In testimony whereof We have hereunto efxed our signatures in the presence ol two subscribing witnesses.
